when playing on a world with this mod and one called arthropod phobia expansion, the game crashed. it was when I was interacting with one of there mobs (something called a centipede evictor larvae) and the game crashed server-side. looking at the crash log, it seems that reliquary might have something to do with it. Here's the log:

I see sinytra connector here and basically something is making the server side logic run in multiple threads when it's something that's supposed to only be run in single thread. Would need this to be narrowed down to the minimal set of mods with which it still happens to be able to do anything here.
